similar old hag experience last night

I had a very similar old hag experience last night.  The first one in a while.  I was almost a sleep and felt someone open handed pop me on the mouth.  Both my arms were down and I was sort of daydreaming, trying to fall asleep and pop.  I jumped out of bed, no body there, just a very eerie feeling o not being alone.  

This of course is not as serious as some of my other attacks, but worth the mention
